Following the Purge a few ISOs managed to escape their genocide and survived as fugitives. Ada and Quorra had been on the run for some time when Ada was critically injured and rendered unconscious. A group of other programs had surrounded the pair when Paige chanced upon the scene and helped the ISOs escape. Paige nursed Ada back to health, but her friends betrayed the fugitives, forcing Ada and Quorra to flee once more.
